Who knew that there were so many places just in the US that were top-secret? Tucked into the side of the Granite Mountains in Little Cottonwood Canyon, Utah, is the Mormon Church Secret Vault. The military-style vault was built in 1965 to hold vital church records, but why do they need it to be so secure?

According to recent reports, it now holds 3.6 billion images, microfilms, and digital media. No one is allowed in without special permission, but we don't think there is much interesting information. Also, why would you want to visit a dark and dingy vault?
